1 answer:

7 0

However, as a result of the Sun's large angular size, solar illumination is only partially blocked in the outer portion of the Earth's shadow, which is given the name penumbra. A penumbral eclipse occurs when the Moon passes through the Earth's penumbra. The penumbra causes a subtle darkening of the Moon's surface.

If I want to accelerate a mass of 3 kg at 5 m/s2 then how much force should I apply?

Stolb23 [73]

Answer: The force that must be applied is 15 N.

Explanation:

Force exerted on the object is defined as the product of mass of the object and the acceleration of the object.

Mathematically,

$F=m\times a$

where,

F = force exerted = ?

m = mass of the object = 3 kg

a = acceleration of the object = $5m/s^2$

Putting values in above equation, we get:

$F=3kg\times 5m/s^2=15N$

Hence, the force that must be applied is 15 N.
